Craig is right. I have never seen a skeptic stop and consider the emotional and psychological damage they cause.
All you need to do damage is have a highly creative and sensitive child and have an authority figure adult who they look up to tell them them that none of the psychic stuff is real. Presto chango, one wrecked life.
No one who is not highly sensitive themselves can really understand why this happens so quickly and does so much damage over such a long period of time. Those who are highly sensitive understand all too well.
